The eligibility ratio of the lenses is enhanced, and it can avoid the problems that the manufacturing efficiency is decreased and the optic property of the optic module of the camera is decreased by smudge.
Description
[technical field]
The invention relates to a kind of plastic lens dust-proof fixture, especially a kind of electrostatic plastic lens dust protector.
[background technology]
Along with development of multimedia technology, digital camera, pick up camera more and more are consumers in general's favor, when people's logarithmic code camera, pick up camera were shot the quality of image proposition requirements at the higher level of object, logarithmic code camera, video camera products demand were also increasing.
In the camera such as digital camera, pick up camera, optical modules such as lens are indispensable parts.In digital camera, pick up camera volume production scheme, high index of refraction optical plastic ejection formation optical module becomes the main flow of digital camera, camera optics assembly.
Yet, this plastic optical element produces static easily on the surface, it is a negative electricity electrically, after eyeglass penetrates and is positioned over the load plate tool certainly, through optical coating and stack-mounted process, glass lens may make neutrality or the electropositivity particle in the environment be adsorbed on the glass lens surface because of the negative electricity on surface, will cause glass lens dirty for this reason, and the production efficiency of eyeglass is reduced, cost also can improve relatively.
[summary of the invention]
In view of this, be necessary to provide a kind of and prevent that glass lens is dirty, the plastic lens dust-proof fixture of raising eyeglass qualification rate.
A kind of electrostatic plastic lens dust protector is used for ccontaining and the fixed plastics eyeglass, and it comprises a load plate, a debris collection section, an insulating barrier and a static field source.This load plate is provided with a plurality of containing holes, and this containing hole is used for ccontaining glass lens; This debris collection section surface can produce static, and this debris collection section can cover ccontaining eyeglass in the load plate; The negative pole of this static field source connects load plate, makes on this load plate and produces negative charge, and the positive pole of this static field source connects debris collection section, makes to produce positive charge on the debris collection section to attract dust.Compared to prior art, described plastic lens dust-proof fixture utilizes electrostatic principle, improve the problem that glass lens adsorbs particle in the environment easily, reduce eyeglass and be subjected to environmental pollution, and improve the eyeglass qualification rate, thereby avoid causing the problem that processing procedure efficient reduces and camera optics module optical property descends because of dirty.

[specific embodiment]
Please refer to Fig. 1 to shown in Figure 3, the better embodiment of electrostatic plastic lens dust protector of the present invention comprises two load plates 10, two debris collection section 20, an insulating barrier and two static field sources 50.Described electrostatic plastic lens dust protector is in order to ccontaining and fixing eyeglass 40, and wherein, this eyeglass 40 is a glass lens, and it comprises optics portion 400 and pedestal 402, and optics portion 400 is positioned at the middle part of pedestal 402, and it is sphere or aspherical surface.
In the present embodiment, described insulating barrier is a plurality of pads 30, and this a plurality of pad 30 is made by insulating material, is located at the place, surperficial upper edges of load plate 10 contiguous logical light portions 120, and does not cover the containing hole 12 on the load plate 10.Debris collection section 20 is attached on the pad 30, covers the surface of load plate 10 contiguous logical light portions 120, thereby covers the optics portion 400 of eyeglass 40, and eyeglass 40 is prevented dust.
In the operating process, place downwards on the surface that a load plate 10 is wherein had logical light portion 120, a plurality of eyeglasses 40 are positioned over respectively in the holding part 122 of a plurality of containing holes 12 on this load plate 10, another load plate 10 is relative with this load plate 10, the logical light portion 120 that is another load plate 10 occupy its holding part 122 tops, and after the optics portion 400 that makes eyeglasses 40 in the logical light portion 120 of its logical light portion 120 and its below load plate 10 or the containing hole 12 aims at, be pressed on this load plate 10 tops, make this two load plates, 10 relative fixed, at this moment, pedestal 402 parts of eyeglass 40 are positioned at the holding part 122 of below load plate 10, and another part is positioned at the holding part 122 of top load plate 10.Simultaneously, the optics portion 400 of eyeglass 40 exposes by the logical light portion 120 of this two load plate 10.On two load plates 10 have the surface of logical light portion 120, place pad 30 respectively, debris collection section 20 is positioned on the pad 30, thereby debris collection section 20 covers the optics portion 400 of eyeglasses 40 in load plates 10 and the containing hole 12 thereof.The positive pole of static field source 50 is connected debris collection section 20, and negative pole connects load plate 10.Because debris collection section 20 is negative electricity with the static that glass lens 40 produces, the particle that originally may be attached on the optical plastic lens 40 can be attracted by debris collection section 20 because of electrostatic force stronger on the debris collection section 20, thereby makes eyeglass 40 can keep clean.
Obviously, described insulating barrier also is substitutable for the insulating coating that is provided with on the debris collection section 20 close surfaces of load plate 10 except that can be pad 30, and then debris collection section 20 directly is attached on the load plate 10 and gets final product.Described load plate 10 can only be one, increase to holding part 122 degree of depth of load plate 10 suitable with pedestal 402 thickness of eyeglass 40, so that eyeglass 40 is placed in it fully, debris collection section 20 and pad 30 are located at load plate 10 both sides, thus the eyeglass 40 that debris collection section 20 is covered in the containing hole 12; Perhaps establish thicker pad 30 on the surface that load plate 10 has a holding part 122, the part of avoiding eyeglass 40 to exceed holding part 122 is exposed and is replaced debris collection section 20, and debris collection section 20 is attached at load plate 10 and has the surface of light hole 120 and have on the holding part 122 lip-deep pads 30, thereby covers the eyeglass 40 in the containing hole 12.
In addition, two load plates, 10 relatively-stationary modes can be the interference fit mode and directly compress; Also can be after two load plates 10 compress, the position that does not coincide with containing hole 12 on this two load plate 10 is provided with a screw two load plates 10 is interfixed.Described two debris collection section 20 can be integrated, with these debris collection section 20 doublings, its broken line is positioned at two load plates 10 and faces the edge that connects, then debris collection section 20 can cover two load plates 10 simultaneously, at this moment, described static field source 50 can be one, and with the positive pole connection debris collection section 20 of static field source 50, negative pole connects two load plates 10 respectively; Obviously; when having only a load plate 10; the broken line of debris collection section 20 is positioned at load plate 10 1 edges; then debris collection section 20 can cover load plate 10 upper and lower surfaces simultaneously; ccontaining eyeglass 40 optics portions 400 both sides all can be subjected to the protection of debris collection section 20 in the load plate 10, and at this moment, described static field source 50 also can be one; the positive pole of static field source 50 is connected with debris collection section 20, and negative pole is connected with load plate 10.
Described plastic lens dust-proof fixture utilizes electrostatic principle, improve the problem that glass lens 40 adsorbs particle in the environment easily, avoid eyeglass 40 to be subjected to environmental pollution, can prevent that glass lens 40 is dirty, and improve the qualification rate of eyeglass 40, thereby avoid causing processing procedure efficient to reduce and problem that the optical property of camera optics module descends because of dirty.
